well in the short run garret yes if you are going to shut your reef down in one year, but it will save in the long run. All I do is buy a thing of calcium aragonite lasts probably over a year depending on calcium requirements, and refill co2 every 6 months-20.00
bottom line pricing is like this
i know you can get a reactor for 200 easily on the used equ. forum, than all you do is get a ph mon. 60.00 and a c02/reg/bubble counter=100.00
you could probably get into a
360 into it most likely. maybe 50 dollars a year to run it. I know how much dosing costs, it wouldnt take long once you get your tanked staked with calcium requiring coral, you will be dosing your pants off. I realize it costs alot but i do see why james recommends it. I was very nervous when i first tried and wish i had people who knew a lick to help me when i took the leap. If you ever get interested garret i will run over and help you set it all up .
there are down sides to ca reactors including higher co2 levels in your tanks, especially in winter time. Also dosing is a pita but it is still just as effective for growth if you keep it consistent and that is where it gets tuff with dosing.
so it really is just a personal decision in the long run.
